Fisheries bycatch as an inadvertent human-induced evolutionary mechanism. [PDF]

PLoS ONE, 2013
Selective harvesting of animals by humans can affect the sustainability and genetics of their wild populations. Bycatch - the accidental catch of non-target species - spans the spectrum of marine fauna and constitutes a harvesting pressure.

Using meta-population models to guide conservation action

Global Ecology and Conservation, 2021
Biodiversity conservation is limited by resources, data, and time for execution. To maximize efficacy, it is best if conservation plans are strategically evaluated for cost, feasibility, and likely impact prior to implementation.

Enhanced data collection in the Canadian Arctic for seabird bycatch information yields highly variable results

Arctic Science
Incidental catch of seabirds (bycatch) in fisheries has been identified as a major threat to the conservation of seabird populations. Acquiring accurate, detailed data on seabird bycatch is an ongoing challenge to effective integrated ecosystem ...

The economic cost of seabird bycatch in Argentinean longline fisheries [PDF]

Bird Conservation International, 2011
SummarySeabird mortality in longline fisheries is believed to be an important cause of the reductions in many seabird populations worldwide, and results in reduced fishing efficiency and economic losses for fishing companies. We estimated the economic cost of not using seabird bycatch deterrents in Argentinean longline fisheries, with the intention of ...

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

Conservation Biology, EarlyView.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Seabird beachcast events associated with bycatch in the Norwegian purse seine fishery

Marine Environmental Research, 2022
Beachcast events, where a large number of seabird carcasses drift ashore, occur with irregular intervals. These events are due to specific situations where mass mortality of seabirds have occurred. Disentangling the cause of these events can provide valuable information on stressors impacting seabird populations. Following several mass mortality events

Evaluating the potential effectiveness of compensatory mitigation strategies for marine bycatch. [PDF]

PLoS ONE, 2008
Conservationists are continually seeking new strategies to reverse population declines and safeguard against species extinctions. Here we evaluate the potential efficacy of a recently proposed approach to offset a major anthropogenic threat to many ...

Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservation

Conservation Biology, EarlyView.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.
